It occurs when healthcare professionals apply knowledge or skills based on misinformation or misconceptions, leading to unintended consequences or adverse outcomes for the patient.

By avoiding misinformation and misconceptions, healthcare professionals can ensure they provide safe and effective care for their patients.
